摘　　要：在船舶设计中,天线布局对于船舶通信品质至关重要。其中,短波天线是船舶通信中的重要组成部分,其布局与船舶通信效率和信号质量紧密相关。文章基于粒子群优化算法研究了短波天线布局,首先在传统粒子群算法基础上提出了一种基于对数函数的可变权值方法,其目的是在迭代初期加快种群寻优速度、提高种群多样性,在迭代后期进行更精细的搜索。将该算法应用于天线布局研究中,通过将短波天线隔离度作为代价函数来不断迭代优化,以给出最优的短波天线布局。最后,将优化后的天线布局带入电磁仿真软件验证。结果证明,该方法能够在设计初期迅速为船舶设计师提供多样的天线布局方案,减少了时间和成本的浪费。In ship design,antenna layout is crucial for the quality of ship communication.Among them,shortwave antennas are an important component of ship communication,and their layout is closely related to the efficiency and signal quality of ship communication.The article studies the layout of shortwave antennas based on particle swarm optimization algorithm.Firstly,a variable weight method based on logarithmic function is proposed on the basis of traditional particle swarm optimization algorithm.Its purpose is to accelerate the optimization speed and improve the diversity of the population in the early stage of iteration,and to conduct more refined search in the later stage of iteration.Apply this algorithm to antenna layout research by iteratively optimizing the shortwave antenna isolation as a cost function to provide the optimal shortwave antenna layout.Finally,the optimized antenna layout will be validated using electromagnetic simulation software.The results show that this method can quickly provide diverse antenna layout schemes for ship designers in the early stages of design,reducing time and cost waste.
